"Vortex™ is an amazing exhaust. We have fitted hundreds and all of our customers are blown away by the extra power and more importantly to the torque. You cannot compete against this system."

“I would like to compliment your company on the workmanship on the exhaust system that was fitted to our Range Rover 2.5 turbo diesel last Wednesday. The fact that the system is now totally free-flowing makes the engine so responsive that it is difficult to resist the temptation ofusing the extra power rather than getting the extra economy.

Knowing that the motor has already done over 120,000 miles it has now jumped from getting 530 miles on a tankfull to just managing 600 miles last weekend. That included twice going through central London and 200 miles up the M1 and back. I am sure that once the novelty of the smooth extra power wears away I will see an even greater fuel economy.”

"I would like to thank all at Vortex for carrying out such a good job on my car. I had heard of you from my partner who had a Vortex system fitted to his Toyota Hi-lux which made a big difference to the car’s performance and fuel consumption.

As you know I brought my 5.7 V8 Cobra Kit Car in to you for the exhaust’s to be modified. The car already had two side pipes fitted by supposed "performance car tuning and exhaust experts" at an extortionate price which made the car very loud but did nothing for performance or consumption. After you had fitted the two new side pipes I immediately noticed a difference in performance and the car now sounds more like a Cobra than a genuine article.

As for consumption I cannot really comment as I have not driven the car very much and after all I did not have new exhausts fitted to a 5.7 V8 420BHP car to reduce fuel consumption! Once again I would like to thank you all for your professionalism and workmanship, I will be recommending you to all at the Cobra Kit Car Club."

"My previous straight-through cat-back system once provided great low rev torque at the cost of peak power, using increased back pressure. The Vortex centre silencer maintained the great low end torque and increased the mid and especially high rev torque. Peak power and hence top speed are noticeably improved. Throttle response is quicker. There's a marked improvement in fuel consumption and the system is quiet, just as I specified. During motorway cruising the exhaust is perfectly silent!!

You really can improve torque throughout the range and peak power with a Vortex cat-back system. I love it!"

"First of all I want to thank Vortex for an excellent job. I travelled to Essex all the way from Scotland to get an exhaust fitted to my Nissan 350z - some people would think I'm mad!!! Well ladies and gents...it was worth the trip and every penny. The exhaust has been made to the exact specification I asked for, which most garages couldn't do. Not only did they manage to fit the exhaust which most garages couldn't do, I also gain a lot of horse-power and the driving is much smoother, no droning noise as most other sport exhausts and it still has got the nice sport sound to it. Best of all I have saved quite a bit of money on fuel since the exhaust has been fitted. This is a serious exhaust....thank you very much to all at Vortex."

"As promised, here are my impressions after a couple of hundred miles of driving with the new Vortex exhaust fitted to my Triumph TR6/Sierra Cosworth mongrel:

I'm very happy with both the fitting of the Vortex exhaust and with the subsequent improvements in performance. I find that the turbocharger spins up more briskly and there is a noticeable improvement in acceleration, especially with small throttle openings at high speed. Overall the performance is sharper and the car is more enjoyable to drive. I've now completed the initial mathematics on fuel consumption. I had to work backwards to calculate my previous mpg but it looks as though the fuel consumption has improved by approximately 15%!"

"All gears have more noticeable power. Foot down in 6th is surprising but all gears have more of an edge and flicking through the gears and engaging in each gear and putting the power down makes you want to have a gearbox full of more gears due to the pick up and you never want to run out of road."

"We have tested Vortex on our own dynamometer equipment and can see the big increase in power and torque, plus a good decrease in fuel consumption from the lambda probe and a drop in emissions. This is the best power enhancing product that I have seen in my twenty years in business. This is free power not obtainable until now! I highly recommend Vortex for petrol or diesel vehicles."

“The best and only exhaust system that achieves substantial increase in performance”

“The Vortex exhaust is the best exhaust there is, it gives power that no other exhaust system can”

“Vortex is an amazing exhaust. We have fitted hundreds and all our customers are blown away by the extra power and more importantly to the torque. You cannot compete against this system”

“To achieve the ultimate performance you need a Vortex, proven time and time again on the rollers”

“Vortex gives and takes tuning to a new level”

“Every customer we have had for a Vortex exhaust has been delighted with the performance. We fitted one to a Skoda Fabia 1.9 TDi and obtained a increase in mpg from 47.4mpg to 53.9mpg (14%)”

”Land Rover Discovery - The Discovery accelerated more cleanly from cruising speed and planting my foot on the floor produced the sort of acceleration I expected from a V8, as I used the new found acceleration quite a number of startled drivers found themselves floundering in the Discovery's wake.”

"Interviewed by BRC’S Simon Moss. Fin stated: "The Vortex made such a difference to the car and it is much more drivable now!” He also told Vortex “The immense difference to the Vortex made was in the corners which allowed him to stay in higher gears and power away in that gear rather than changing down, and there was no turbo lag. The increased torque along the rev range made the BMW a much more powerful vehicle"

"Idle is smoother and quieter. Throttle response is livelier and I am having to re-educate my right foot to throttle control. More torque appears to be available at lower revs."

"There is no question that the Vortex draws out more smoothly and rapidly (you can witness this just from the exhaust note and noticeably smoother gas flow from the tailpipe even at tickover). That easy flow of exhaust translates into more fluid acceleration which is immediately evident."

"We have tested the car at UK circuits and laptimes have been reduced and power and torque upon acceleration has shown an improvement and all within the race regulations."
